ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 484,372, dated October 11, 1892.

Application filed October 20, 1890. Serial No. 368,635- (No model.)

To all whom it may concern:

Be itknown that I, J AOOB W. KOHN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Envelopes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to enable an envelope to be readily and quickly opened without recourse to a knife or other extraneous means or without tearing it open, and thereby possibly tearing or rnutilating the inclosure, and to provide against the formation of loose cord ends, such as are common in other envelopes having cords arranged permanently in the envelopes to allow of convenient opening.

The invention consists in the improved envelope and in the arrangements and combi nation of the several parts thereof, as herein set forth, and finally pointed out in the claim.

Referring to the accompanying drawings, in which similar letters of reference indicate corresponding parts in .each of the figures where they occur, Figure 1 represents in plan an envelope embodying-my improvement as it appears when scaled up, and Fig. 2 is a similar view indicating the method by which the envelope is opened.

In said drawings, a, indicates the ody of the envelope, and b a fine cord or filament, which is inserted between the thicknesses of the paper where the same is folded and extends vthe full length or width, as the case may be, of the envelope, though in the drawings it is shown to be lengthwise, the ends of the thread or cord being firmly cemented or otherwise secured to the paper.

About half-way between the extremities of the envelope an oblong recess 0 is cut in the edge thereof, leaving a section of the cord exposed and free to be conveniently grasped by the fingers, the ends of the cord being held,

however, by the folded paper at the opposite ends of said recess. The oblong finger-recess admits of a considerable exposure of cord without extending deep into the edge of the envelope and thus exposing the letter or contents thereof to View. The finger perforation or recess is made, and the cord extending across the same is arranged at the edge opposite the opening for the insertion of the letter or at one of the ends, and thus the cord when fastened at the inside is never exposed, so as to be forced easily from its fastened relation, all as indicated in Fig. 1. In lieu of the oblong recess in the edge of the envelope a long incision or series of perforations may be made 'just back or inside of the cord, the object of which is to enable a person desiring to open the envelope to conveniently seize the cord and to accomplish the opening by pulling smartly outward thereon, which results in neatly cutting or tearing the envelope open without injury to the contents thereof, as will be readily understood upon reference to Fig. 2. The cord extends across said opening and enters at the opposite ends thereof into the folds of the envelope, and thus there are no unsightly loose ends and the cord is always free and clear from the paper and in a position convenient for grasping, and the objection heretofore common to the class of the free ends becoming folded or turnedinto the fold of the paper and thus inconvenient for grasping is avoided.

Having thus described my invention, what I claim as new is The envelope provided with a perforation located midway on a line with the crease or fold of one of the end or side flaps, in combination with the cord or thread which passes through said opening or perforation and has its inner ends gummed or secured to the opposite corners of the envelope, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of October, 1890.

JACOB \V. KOHN.
